Summary

The purpose of this study is to evaluate whether a new type of imaging study, called 18F-Clofarabine (CFA) PET/CT, can be used to image cancer pyrimidine metabolism in participants.

PET (positron emission tomography) imaging is a way of looking at cancers that can reveal cancer metabolism. Presently, however, there are no imaging agents in routine use to look at an aspect of cancer metabolism (pyrimidine metabolism) that dictates whether certain cancer drugs, e.g., gemcitabine, are likely to be taken into the cancer cells. This clinical trial will be testing whether 18F-Clofarabine (CFA) could be an imaging agent to measure this aspect of cancer metabolism.

18F-Clofarabine

The participants enrolled will receive a baseline CFA PET/CT evaluation. Then, the participants will undergo the routine follow up would normally occur for their cancer and its treatment. If this routine follow up and care involves repeat imaging of the cancer, then the CFA PET/CT scan will be repeated at that time (timed according to standard-of-care follow-up imaging), which is expected between a month to about 4 months after the first CFA PET/CT scan. The study period will end 24 hours after this repeat PET/CT scan.
